What are the teaching characteristics of Nanjing First Middle School? The school is not good?

My child is on a Chongwen class, Chongwen class is very difficult to test, not want to enter into the science intensive class is to enter the school score high admission score 10 points will be selected to go, and each semester will be rolling, not good to go out, good to go in. Chongwen class is in the science class before the beginning of the school year and add the examination selected, but this year is a separate first test. In the examination before the examination Chongwen class will have a lot of activities, and is sponsored, on a lot of extracurricular subjects, is free. However, if their own homework are self-care, it is difficult to stay in Chongwen class, in fact, or according to their own situation to decide, in fact, to the second half of the sophomore year of high school or even may be divided into classes, some of the activities of Chongwen class is less.
